Deleting and Adding Lists in Java Applets

[Bomber_Will]

The coding to this is in my other topic on this section but I'm not allowed to link until I have a post count of 20.

Is their a way to make a choice list in the applet that when you pick on a choice, creates a new list? Then if the user picks a new choice from the first list, it deletes the second list and makes a new list.

Example:
-User opens the applet and sees List 1 with Choice A, Choice B, Choice C.
-User picks Choice A from List 1 and it creates a List 2 with Choice D, Choice E, Choice F
-User goes back to List 1 and picks Choice B
-List 2 gets deleted and List 3 is created with Choice G, Choice H, Choice I

The only way I'm thinking is to make a class per choice but I don't even know if that would delete automatically or not and I am not sure how to delete specific things. Last time I tried to delete one list, I managed to delete everything but the first Label created.

Have you looked into JListControl?

I just looked into JList and it seems that clear() method almost does what I want. I just need to find a way for it to clear 1 section instead of the entire applet. Thanks, i'll keep looking.

Very likely, what you need to do is call new on each new List, depends on system loading and so on. For each section, have one list. You can have an array of Lists or a list of lists. Sounds like new operator is what you want.

I saw somewhere that they had a list, cleared it, and put it back along with a new option and new lists under it. That would be a way to get what I want and it seems pretty easy to do. I found a few books that'll help me with my second problem of connecting to a database, hopefully I can make sense out of it so I can knock out the connecting to a database and this list problem at the same time.
